A new modification of the Ritter reaction using trimethylsilyl cyanide (Me3SiCN) is described, which converts alcohols to their corresponding formamides in high yields using a convenient procedure. The reaction conditions and mechanism are discussed. In some cases, new formamides are synthesized which cannot be prepared by the classical Ritter reaction.
Electron-Transfer Substitution Reactions: Facilitation by the Cyano Group

It is now clear that a cyano group facilitates electron-transfer substitution reactions.Of particular interest is the demonstration that electron-transfer chain substitution at a saturated carbon atom has been achieved in the absence of a nitro group.

Poly(isocyanides), (RN=Cn, can be prepared from isocyanides, , by the catalytic action of nickel(II) compounds.The main chain of these polymers is a rigid helix.This helical conformation results from a restricted rotation around the single bonds that connect the main-chain carbon atoms.Polymerization of achiral isocyanides generally gives a racemic mixture of left- and right-handed helices, whereas polymerization of optically active isocyanides results in helices with an excess of one screw sense.We describe a procedure for obtaining poly(isocyanides) with predominantly one screw sense, starting from an achiral monomer.A catalyst is prepared by adding an optically active amine to a tetrakis(isocyanide)nickel(II) perchlorate complex.Polymerization of various achiral isocyanides with this catalist yields optically active polymers with an enantiomeric excess up to 83percent.
